"I am in my seventies and my doctor asked me to try and wean myself off of Ambien by using this new drug called Belsomra. Last night using the drug for the first time I had the one of the worst nights of my life. I had horrific and frightening nightmares where I felt like I was awake but I couldn't get up and I never felt like I went into a deep sleep.  All day long today I have felt like I'm in a fog and my equilibrium is off. I will never use this drug again it is a nightmare in itself."
